摘　　要：针对风力发电功率波动和并网弃风严重问题,采用含氢储能管理系统的风氢耦合发电系统及其协同控制策略.风氢耦合系统由风电场与氢储能管理系统(包括电解槽、燃料电池、储氢罐等)构成,各单元通过功率变换器汇集到并网点,与交流电网相连.综合考虑储能荷电状态、储能出力及相关约束限制导致并网点电压波动,引入超级电容器用以减少并网点电压变化.在电解槽启动优先级高于超级电容的前提下,采用3种运行状态下的系统协同控制策略.通过Matlab/Simulink软件进行仿真研究,验证了风氢耦合系统协同控制策略的有效性,提高了风电的消纳能力.Aiming at the serious problem of wind power generation caused by wind power fluctuation,the hydrogen-hydrogen coupling power system with hydrogen storage management system is adopted to improve the capacity of wind power.The wind-hydrogen coupling system consists of wind farm and hydrogen storage management system（ including electrolytic cell,fuel cell,hydrogen storage tank,etc.）,the unit through the power converter pooled into the network,connected with the AC power grid.Considering the energy storage state,energy storage output and related constraints limit the voltage fluctuations caused by the network,the introduction of super capacitors to reduce the network voltage changes.Under the premise that the priority of the cell is higher than that of the super capacitor,the system cooperative control strategy is considered under three operating conditions.The simulation results of Matlab/Simulink software are used to verify the effectiveness of the cooperative control strategy of wind-hydrogen coupling system.
